“Christie vetoed a marriage equality bill last year, denying thousands of New Jerseyans equality,” O’Malley wrote in the email touting state Sen. Barbara Buono (D) for governor, as quoted by the Star-Ledger. “We have a chance to defeat him and make real progress, but we need you today.”

"I was honored to lead the fight for dignity and equality in Maryland,” he continued. “And today I strongly support Barbara Buono, who can finally defeat Chris Christie and make sure that New Jersey is no longer the only state in the Northeast that doesn't recognize marriage equality.”

Christie also criticized the Supreme Court's striking down of the Defense of Marriage Act (DOMA) last month as a "bad decision."
